I'm with Jewel654, have you looked at the porcelains? Here is a few that I was looking at. I went with the large one shown here in the center. Thats a pan of snow. The large tile is called Atlas Concorde, Marvel Calacatta Extra, and is from Italy. I chose the matte finish, and this sample is matte. I bought it through Nebraska Furniture Mart. They were very helpful and gave me a discount as well. The other tiles shown are a variety of other tile samples. The tile is ever so slightly warm and looks beautiful with my walnut vanity and woodwork in the bathroom that I finished this past summer:

A couple of comments. Before you use marble in the shower, make sure you know all the cons. You know the pro--it looks fabulous and rich, especially right after it's installed. Cons--One--it's expensive (the mosaic), so it needs to be done correctly or you will waste precious $$$. Two--it will react with any liquid that comes in contact with it--soap, shampoo, body wash, hair dye, even water. You can't use bleach on it so the grout can become discolored and dirty. As an accent it would be fine, but to surround it with marble tiles could lead to problems. On the walls and floor, it isn't the best choice. (Ask me how I know.) Another comment is that the framed tile is "dated." Oh how I hate that word. Your inspiration bathroom is beautiful and the framed marble is lovely, and the workmanship looks great. I would place it on the wall just as shown, where it is visible the moment you enter the room. Surround it with plain white tiles, either rectangular or square, 2x6, 3x5, 4x4, 6x6, etc. I'd rather see a framed panel done well than a haphazard attempt at scribing it to the field tile. No to adding it to the wall with the shower controls.

is this for a tub? That large tile, it's going under the tub on this cement board? or is this a shower floor? I hope its not a shower floor! That wood curb also needs to be completely covered. Can we see how the shower is being formatted for the waterproofing? what if you stacked the large tile on the floor? basically like this. (I think it's too large for that small space. there's going to be a lot of cuts, which is a waste for this large format tile) any chance of doing something diff on the floor? diff tile altogether? you're doing the plain white tile on the wall, the hex on the shower floor, and then you have the small space for the other tile? is the shower tile going in like this? (you'll notice the square tiles on either side in the white) you could do a larger hex tile (this is a 2") and use it for all of the floors. you doing a niche? w/the hex tile? I did this layout for my neighbor. used a recycled white glass tile for the niche. (it's not green) or, do a larger, darker hex or something like this gray I'd rather use a longer tile for the shower, like this. can you get that tile in a larger size? you could use this tile on the outside floor in a herringbone or some other layout even this size is better. looks like a 3x12. you could do this on the floor in a diff type of layout I like this basketweave layout or, try a terrazzo look 24x24 size tile for the floors

James, if you're on a budget, can you do some simple DIY projects? If you must keep that vanity, paint it. change the hardware. This green could work nicely w/your black granite. You'd have to get a black faucet, something a little higher like shown below. there are some inexpensive ones. Also, get some simple molding to go around your mirror and paint it black. new light. shower curtain (to conceal the shower until you can redo) Did you know you can paint that ceramic tile floor? until you can save enough to do the whole bathroom, it's worth a shot. I can give you a link to it if you're interested. You'd do a solid base coat, and then do something simple like this triangle, randomly, w/a similar green shade. Or, get a stenciland do something like this (there are tons of designs you could do and combos of colors) If you want to do a white vanity, here ya go. New light, black frame, black or nickel hardware, paint the tile in a black/white stencil design, Boho shower curtain, wall color white, and paint your bathroom door this Wrought Iron shade. Here's how that looks w/the black and white some other color combos You could also frame your mirror with wood, or some other type of color molding. (just google "how to frame vanity mirror". This reclaimed wood frame would look good w/the color combo right above^ Have you ever painted something like that? it's not difficult. You need to remove the doors (number them) to a place where you can sand everything (the cab itself you'll sand in the bathroom)with a 150 grit, then do a 220, and finally a 320. when done, wipe w/mineral spirits, Prime w/Zinsser oil base primer. I get the spray can because it's a lot easier. (you'll have to cover everything in your bathroom while spraying the cabinet. otherwise, use a brush and a can of the primer). once it's all primed, sand w/a 220 grit very lightly just to smooth out the rough feeling. Use your hands to feel the finish top coat. clean and wipe w/a damp rag. Make sureyou wipe everytthing thats getting painted. I suggested the shower curtain to hide the current shower tile. Don't do that until you're ready to do everything else. You could have the shower tile epoxy coated w/a bright white. cost is about $400 or so. I'd get rid of those shower doors for now. Or, give them a really good cleaning. you can still use the shower curtain to cover it though. You said you liked that montgomery tile (the ribbon one) Here it is in the black (comes in white and gray too) this isn't completely wiped and clean, so keep that in mind. you could remove your tub and just do a shower like this This is a porcelain floor tile Or, here's that Emser Terrazio tile in the black. would look nice w/the white vanity and your black granite (unless you plan on completely changing all of that In that case you could do a new vanity w/diff top, and do the shower and floor like this. Notice the shower doors. black floor, shower floor and white shower tile walls and vanity. notice how they did the art over the towel bar and a shower curtain. no tub. as for the vanity, if you can't paint, look on craigslist or facebook marketplace for a good deal on vanities. sometimes you luck out and can find one w/sink and countertop included.
